Description

Technical Field

[0001] The utility model relates to the technical field of sintering machines, in particular to a novel sintering machine material surface adjustment roller device. Background Art

[0002] The sintering production process includes batching, mixing, pelletizing, feeding, ignition and sintering. Among them, the feeding process of the sintering machine trolley is an important link in the sintering production process. The feeding quality will directly affect the airflow distribution of the sintering material layer, thereby affecting the permeability and vertical sintering speed of the material layer, and ultimately affecting the mineralization quality of the sintered ore and the energy consumption of sintering electricity.

[0003] At present, the domestic sintering machine trolley material distribution process generally only adopts an integral or segmented flat feeder, which can only "passively" perform material pressing, cannot achieve flexible adjustment, and cannot effectively improve the permeability of the sintering material layer. At the same time, it will also cause serious material leakage on both sides of the trolley, poor edge distribution effect, and the "edge effect" on both sides of the sintering machine trolley will be aggravated, affecting the quality of sintered ore. Therefore, a new type of sintering machine material surface adjustment roller device is proposed to solve the above problems. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a new type of sintering machine material surface adjustment roller device, which has the advantages of reducing the "edge effect" of material distribution on both sides of the sintering machine trolley, leveling the material surface, reducing the sintering return rate, and improving the quality of sintered ore. It solves the problem that the domestic sintering machine trolley material distribution process generally only uses an integral or segmented flat material device, which can only "passively" perform material pressure processing, cannot achieve flexibility adjustment, and cannot effectively improve the air permeability of the sintering material layer. At the same time, it will also cause serious material leakage on both sides of the trolley, poor edge material distribution effect, and aggravate the "edge effect" on both sides of the sintering machine trolley, affecting the quality of sintered ore.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a novel sintering machine material surface adjustment roller device, comprising a sintering machine trolley, wherein a material surface adjustment device is provided on the lower side of the sintering machine trolley;

[0006] The adjusting device includes two fixed brackets fixedly connected to the lower side of the sintering machine trolley, a slider slidably connected to the opposite sides of the two fixed brackets, a screw rod fixedly connected to the upper side of the slider, two bolts threadedly connected to the outside of the screw rod, a sleeve sleeved on the outside of the screw rod and a pressure roller device arranged on one side of the sleeve.

[0007] Furthermore, the pressure roller device includes a fixed sleeve fixedly connected to one side of the sleeve, bearings sleeved on the left and right sides of the inner wall of the fixed sleeve, a cylindrical roller sleeved between the two bearings, and a force-bearing structure arranged outside the fixed sleeve.

[0008] Furthermore, the force-bearing structure includes two connecting brackets fixedly connected to the outside of the fixing sleeve and a limiting sleeve slidably sleeved on the outer wall of the upper end of the connecting bracket.

[0009] Furthermore, a slide groove matched with the slider is provided on opposite sides of the two fixed brackets, and the slider is slidably connected in the slide groove on one side close to the fixed bracket.

[0010] Furthermore, a mounting hole matching the bottom of the screw rod is provided inside the sliding block, and the lower side of the screw rod is fixedly inserted in the mounting hole.

[0011] Furthermore, the upper side of the limiting sleeve is sleeved on the lower surface of the sintering machine trolley.

[0012] Furthermore, the fixing bracket is a V-shaped structure, and the connecting bracket is a T-shaped structure.

[0013] Compared with the prior art, the utility model provides a new type of sintering machine material surface adjustment roller device, which has the following beneficial effects:

[0014] 1. The new sintering machine material surface adjustment roller device can adjust the height of the cylindrical roller connected to one side of the fixed sleeve between the two fixed brackets by rotating the two bolts on the outside of the screw. At the same time, the bolts can also limit the movement of the sleeve to adapt to the changes in the permeability of different material types, thereby ensuring a stable sintering speed.

[0015] 2. The new sintering machine material surface adjustment roller device presses the material by rotating the cylindrical roller, and the sliders on both sides slide in the chute to avoid hindering the rolling pressing of the cylindrical roller. This solves the problem that the domestic sintering machine trolley material distribution process generally only uses an integral or segmented flat feeder, which can only "passively" perform material pressing, cannot achieve flexible adjustment, and cannot effectively improve the permeability of the sintering material layer. At the same time, it will also cause serious material leakage on both sides of the trolley, poor edge distribution effect, and aggravate the "edge effect" on both sides of the sintering machine trolley, affecting the quality of sintered ore.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 In this embodiment, a novel sintering machine material surface adjustment roller device comprises a sintering machine trolley 1, and a material surface adjustment device is arranged at the lower side of the sintering machine trolley 1. The adjustment device comprises two fixed brackets 2 fixedly connected to the lower side of the sintering machine trolley 1, a slider 3 slidably connected to the opposite side of the two fixed brackets 2, a screw rod 4 fixedly connected to the upper side of the slider 3, two bolts 5 threadedly connected to the outer side of the screw rod 4, a sleeve 6 sleeved on the outer side of the screw rod 4, and a roller device arranged at one side of the sleeve 6.

[0022] Among them, the pressure roller device includes a fixed sleeve 7 fixedly connected to one side of the sleeve 6, bearings 8 sleeved on the left and right sides of the inner wall of the fixed sleeve 7, a cylindrical roller 9 sleeved between the two bearings 8 and a force-bearing structure arranged on the outside of the fixed sleeve 7, the force-bearing structure includes two connecting brackets 10 fixedly connected to the outside of the fixed sleeve 7 and a limiting sleeve 11 slidably sleeved on the outer wall of the upper end of the connecting bracket 10, and the two fixed brackets 2 are provided with a slide groove 12 matched with the slider 3 on the opposite side, and the slider 3 is slidably connected in the slide groove 12 on the side close to the fixed bracket 2, and a mounting hole matched with the bottom of the screw rod 4 is provided inside the slider 3, and the lower side of the screw rod 4 is fixedly inserted in the mounting hole, and the upper side of the limiting sleeve 11 is sleeved on the lower surface of the sintering machine trolley 1, the fixed bracket 2 is a V-shaped structure, and the connecting bracket 10 is a T-shaped structure.

[0023] It should be noted that while the cylindrical roller 9 slides back and forth between the two fixed brackets 2, the upper end of the connecting bracket 10 slides up and down in the limiting sleeve 11, which increases the force on the entire cylindrical roller 9 and ensures the safe and stable operation of the cylindrical roller 9. The connecting brackets 10 are respectively fixed to the positions opposite to the fixed sleeve 7 on the outside of the cylindrical roller 9, and the connecting bracket 10 is arranged on a side away from the sleeve 6. The upper side of the fixed bracket 2 is welded and fixed to the bottom of the sintering machine trolley 1, and is 100 mm away from the trolley guardrail of the sintering machine trolley 1 to prevent interference with the forward movement of the sintering machine trolley 1. The connecting bracket 10 is also fixed to the surface of the fixed sleeve 7 by welding.

[0024] The working principle of the above embodiment is:

[0025] During the rolling pressing of the cylindrical roller 9, the cylindrical roller 9 is slidably connected in the slide groove 12 opened on the surface of the fixed bracket 2 through the slider 3 connected to the outside, so as to avoid obstruction to the rolling pressing of the cylindrical roller 9. The bearing 8 on the inner wall of the fixed sleeve 7 cooperates with the cylindrical roller 9 to reduce the obstruction to the cylindrical roller 9. When the cylindrical roller 9 slides to press the material, the upper end of the connecting bracket 10 moves synchronously in the limiting sleeve 11, which effectively increases the force on the outer side of the cylindrical roller 9. When it is necessary to adjust the height according to the pressing of different materials by the cylindrical roller 9, the bolts 5 on the upper and lower sides of the sleeve 6 are rotated at the same time to adjust the height of the sleeve 6, and the cylindrical roller 9 connected to the sleeve 6 is adjusted upward or downward to change the distance between the material and adapt to the changes in the permeability of different material types, thereby ensuring a stable sintering speed and accurately controlling the amount of pressure on the material surface.
